Description

La présente invention concerne un dispositif pour assommer par décharge électrique des animaux destinés à l'abattage.The present invention relates to a device for knocking out animals intended for slaughter by electrical discharge.

On connait déjà de tels dispositifs du type comportant d'une part des moyens d'acheminement des animaux constitués de deux tapis sans fin se faisant face et inclinés de façon à former un passage en forme de V, et d'autre part deux électrodes effaçables mobiles entre une première position active pour laquelle elles sont placées de part et d'autre de la tête de l'animal et une seconde position effacée permettant le dégagement de l'animal assommé.We already know such devices of the type comprising on the one hand means for transporting animals consisting of two endless belts facing each other and inclined so as to form a V-shaped passage, and on the other hand two erasable electrodes movable between a first active position for which they are placed on either side of the head of the animal and a second erased position allowing the release of the stunned animal.

Dans de tels dispositifs, lorsque l'on veut éviter une application manuelle des électrodes, coûteuses en main d'oeuvre et non exempte de danger, les électrodes sont montées sur un équipage entrainé à l'aide d'organes moteurs entre les deux positions extrêmes, comme dans la demande de brevet européen N° 019 332.In such devices, when it is desired to avoid manual application of the electrodes, which are labor-intensive and not free of danger, the electrodes are mounted on a crew driven by means of drive members between the two extreme positions , as in European patent application No. 019 332.

Cette dernière disposition conduit à des constructions lourdes, onéreuses et complexes. Ces systèmes n'assurent pas le synchronisme rigoureux (qui est nécessaire) entre l'avancement de l'animal (sur les tapis d'entrainement) et le charriot porte-électrode.This latter arrangement leads to heavy, expensive and complex constructions. These systems do not ensure the rigorous synchronism (which is necessary) between the advancement of the animal (on the training mats) and the electrode-carrying cart.

La demande de brevet européen N° 067 482 prévoit la suspension des électrodes à un système pendulaire, lequel cependant suit un parcours courbe donc non parallèle au parcours linéaire de la tête de l'animal.European patent application No. 067 482 provides for the suspension of the electrodes to a pendulum system, which however follows a curved path therefore not parallel to the linear path of the head of the animal.

La présente invention concerne un dispositif pour assomer par l'électricité les animaux de boucherie de construction simple et de fonctionnement fiable et sûr et qui assure un parcours à la fois rigoureusement synchrone et rigoureusement parallèle entre les électrodes et la tête de l'animal pendant leur temps de contact nécessaire pour assurer l'électrocution de l'animal.The present invention relates to a device for knocking down electrically slaughter animals of simple construction and reliable and safe operation and which ensures a path which is both strictly synchronous and strictly parallel between the electrodes and the head of the animal during their contact time necessary to ensure electrocution of the animal.

A cet effet l'invention concerne un dispositif pour assommer par décharge électrique des animaux de boucherie en cours d'abattage, du type comportant des moyens d'acheminement desdits animaux et au moins deux électrodes montées sur un chariot support, lequel est déplaçable le long d'un chemin de guidage parallèle au moyen d'acheminement des animaux entre une première position active pour laquelle les électrodes sont aptes à prendre place de part et d'autre de la tête de l'animal et une seconde position effacée permettant l'évacuation de l'animal et ce dispositif est caractérisé en ce que le chariot porteur des électrodes est monté sur roulement libre et il est déplaçable le long du chemin de guidage depuis sa position active vers sa position effacée sous la seule poussée de l'animal et d'autre part en ce que le chemin de guidage et les moyens d'acheminement des animaux sur la partie parallèle de leur parcours, suivent des directions parallèles inclinées vers le haut (dans le sens allant de la position active vers la position effacée), le chariot étant ainsi apte à accompagner le mouvement d'avancement de l'animal en cours d'électrocution et après la chute de l'animal assommé, à redescendre librement par gravité jusqu'à la position de départ A pour desservir l'animal suivant.To this end, the invention relates to a device for knocking out slaughter animals by slaughter during slaughter, of the type comprising means for conveying said animals and at least two electrodes mounted on a support carriage, which is movable along a guide path parallel to the means for conveying the animals between a first active position for which the electrodes are able to take place on either side of the animal's head and a second erased position allowing evacuation of the animal and this device is characterized in that the carriage carrying the electrodes is mounted on a free bearing and it is movable along the guide path from its active position to its erased position under the sole push of the animal and d on the other hand in that the guide path and the means of transporting the animals on the parallel part of their route, follow parallel directions inclined upward (in the allan direction t from the active position to the erased position), the carriage thus being able to accompany the advancing movement of the animal during electrocution and after the knocked animal has fallen, to descend freely by gravity until the starting position A to serve the next animal.

Ainsi, le mouvement des électrodes est réalisé automatiquement et sans dépense d'énergie puisque à partir de la première position active, celles-ci sont entrainées par la tête même de l'animal selon un parcours rigoureusement parallèle et synchrone entre les électrodes et la tête sur laquelle elles sont appliquées ; après quoi ces électrodes sont ramenées dans la position initiale de départ, par simple gravité.Thus, the movement of the electrodes is carried out automatically and without energy expenditure since from the first active position, they are driven by the head of the animal according to a strictly parallel and synchronous path between the electrodes and the head on which they are applied; after which these electrodes are returned to the initial starting position, by simple gravity.

Afin de faciliter le retour des électrodes, le chemin de guidage est parallèle sur une première partie de sa longueur aux moyens d'acheminement des animaux et divergent vers le haut sur la seconde partie de sa longueur.In order to facilitate the return of the electrodes, the guide path is parallel over a first part of its length to the means for transporting the animals and diverges upwards over the second part of its length.

L'invention sera bien comprise à la lumière des dessins annexés.The invention will be clearly understood in the light of the accompanying drawings.

  • La figure 1 est une vue de côté d'un exemple de réalisation du dispositif selon l'invention dans lequel la direction d'avancement des animaux est inclinée sur l'horizontale.Figure 1 is a side view of an exemplary embodiment of the device according to the invention in which the direction of advancement of the animals is inclined to the horizontal.
  • La figure 2 est une vue de face d'un dispositif dans lequel la direction d'avancement des animaux est horizontale.Figure 2 is a front view of a device in which the direction of advancement of the animals is horizontal.
  • La figure 3 montre une vue en perspective, d'une variante du dispositif.Figure 3 shows a perspective view of a variant of the device.
  • La figure 4 montre une vue en coupe transversale du dispositif de la figure 3.FIG. 4 shows a cross-sectional view of the device of FIG. 3.

Le dispositif 1 montré sur les figures est du type comportant des moyens d'acheminement 2 constitués de deux tapis sans fin 3 et 4 se faisant face et inclinés de façon à former un passage 5 en forme de V dans lequel les animaux 6 et 7 sont entrainés en translation, en portant par leurs flancs sur les parois en regard des tapis sans fin 3 et 4.The device 1 shown in the figures is of the type comprising conveying means 2 consisting of two endless belts 3 and 4 facing each other and inclined so as to form a passage 5 in the form of a V in which the animals 6 and 7 are driven in translation, by carrying by their sides on the walls facing the endless belts 3 and 4.

Le dispositif selon l'invention comporte également une paire d'électrodes 8 et 9 effaçables et mobiles.The device according to the invention also comprises a pair of erasable and mobile electrodes 8 and 9.

A cette fin, les électrodes 8 et 9 sont solidaires d'un chariot 10 monté sur des roulements libres latéraux 11 et 12 et déplaçables le long de moyens de guidage constitués de deux rails 13 et 14 parallèles entre eux aptes à recevoir les organes de roulement.To this end, the electrodes 8 and 9 are integral with a carriage 10 mounted on free lateral bearings 11 and 12 and movable along guide means consisting of two rails 13 and 14 parallel to each other capable of receiving the running gear.

Le chemin de guidage défini par les rails de guidage 13 et 14 comporte une première partie 15 parallèle à la direction d'avancement des animaux (flèche F) et une seconde partie 16 divergeant vers le haut par rapport à la première partie 15.The guide path defined by the guide rails 13 and 14 comprises a first part 15 parallel to the direction of advancement of the animals (arrow F) and a second part 16 diverging upwards relative to the first part 15.

Selon l'exemple de la figure 1, la direction d'avancement des animaux est inclinée par rapport à l'horizontale, il en est de-même en conséquence de la première partie 15 du chemin de guidage du chariot 10 portant les électrodes 8 et 9.According to the example of FIG. 1, the direction of advancement of the animals is inclined relative to the horizontal, it is the same as a consequence of the first part 15 of the guide path of the carriage 10 carrying the electrodes 8 and 9.

Le chariot 10 est susceptible de se déplacer librement le long des rails de guidage 13 et 14 grâce à ses organes de roulement libre 11 et 12.The carriage 10 is capable of moving freely along the guide rails 13 and 14 thanks to its free rolling members 11 and 12.

Le fonctionnement du dispositif est décrit ci-après.The operation of the device is described below.

Les animaux 6 et 7 sont acheminés grâce aux tapis sans fin 3 et 4 dans la direction et le sens indiqués par la flèche F de la figure 1.The animals 6 and 7 are conveyed by means of the endless belts 3 and 4 in the direction and the direction indicated by the arrow F in FIG. 1.

Les électrodes 8 et 9 sont disposées dans le passage 5 de manière qu'elles puissent être placées de part et d'autre de la tête de l'animal.The electrodes 8 and 9 are arranged in the passage 5 so that they can be placed on either side of the head of the animal.

En position de départ, les électrodes sont la première position extrême A, c'est-à-dire le plus bas et le plus en arrière de la course possible du chariot 10.In the starting position, the electrodes are the first extreme position A, that is to say the lowest and the most back of the possible travel of the carriage 10.

Le premier animal, en l'occurrence des porcs selon l'exemple des figures, arrive et place sa tête entre les électrodes. L'animal 6 continuant sa course entraîne les électrodes dans son mouvement selon la flèche G de la figure 1, jusqu'à une position intermédiaire B ou des contacteurs ou détecteurs de position ferment le circuit électrique reliant les électrodes à une source de courant électrique (non représentés).The first animal, in this case pigs according to the example of the figures, arrives and places its head between the electrodes. The animal 6 continuing its course drives the electrodes in its movement according to the arrow G in FIG. 1, to an intermediate position B or contactors or position detectors close the electrical circuit connecting the electrodes to a source of electric current ( not shown).

A partir de cet instant, la tête de l'animal reçoit un courant électrique qui la traverse latéralement.From this moment, the head of the animal receives an electric current which crosses it laterally.

Les tapis d'acheminement 3 et 4 poursuivant leur course entrainent l'animal et les électrodes toujours disposées de part et d'autre de la tête de l'animal, jusqu'à une autre position intermédiaire C où des seconds contacteurs ou détecteurs (connus en eux-mêmes) ouvrent le circuit électrique, supprimant ainsi la liaison des électrodes avec la source d'énergie électrique.The conveyor belts 3 and 4 continuing their course drive the animal and the electrodes always disposed on either side of the animal's head, to another intermediate position C where second contactors or detectors (known themselves) open the electrical circuit, thereby removing the connection of the electrodes with the source of electrical energy.

Le mouvement d'avancement des animaux se poursuit jusqu'à l'extrémité des tapis 3 et 4 où l'animal 17, n'étant plus soutenu par ces derniers, tombe sur le sol 18 ou sur un plan incliné ou table de desserte 19. Il est à noter qu'à partir de la position C, l'animal est assommé.The movement of advancement of the animals continues until the end of the belts 3 and 4 where the animal 17, no longer supported by the latter, falls on the ground 18 or on an inclined plane or serving table 19 It should be noted that from position C, the animal is knocked out.

Le chariot 10 étant monté libre sur les rails 13 et 14 inclinés sur l'horizontale, est rappelé en sa première position active extrême A par simple gravité. Il roule donc le long des rails 13 et 14 jusqu'à atteindre cette position A, où des organes d'arrêt sont prévus et pour laquelle les électrodes sont prêtes à desservir l'animal suivant.The carriage 10 being mounted freely on the rails 13 and 14 inclined to the horizontal, is recalled to its first extreme active position A by simple gravity. It therefore rolls along the rails 13 and 14 until it reaches this position A, where stop members are provided and for which the electrodes are ready to serve the next animal.

De manière avantageuse, la seconde position effacée D est placée sur la seconde partie divergente 16 des rails de guidage 13 et 14. Le point de courbure 22 entre la première partie 15 et la seconde partie 16 est donc disposé à proximité et juste en amont (suivant le sens d'avancement des animaux) de la position extrême effacée D.Advantageously, the second erased position D is placed on the second divergent part 16 of the guide rails 13 and 14. The point of curvature 22 between the first part 15 and the second part 16 is therefore arranged at proximity and just upstream (according to the direction of advance of the animals) of the erased extreme position D.

Ainsi, les électrodes 8 et 9 s'écartent vers l'avant du passage 5, dès que le chariot 10 parvient sur la seconde partie divergente 16 des rails de guidage, ainsi que montré par la position extrême effacée D de la figure 1.Thus, the electrodes 8 and 9 deviate towards the front from the passage 5, as soon as the carriage 10 reaches the second divergent part 16 of the guide rails, as shown by the erased extreme position D of FIG. 1.

Selon les figures 3 et 4, le chariot 23 (schématisé sur la figure 1) supporte l'ensemble porte électrodes constitué notamment des deux boîtiers 25 et 25' en forme de pyramide tétraédrique. Cette pyramide comporte notamment vers l'aval, c'est-à-dire en le sens de l'avancement de l'animal symbolisé par la flèche F1, un flanc 26 et 26', les deux flancs 26 et 26' constituant entre eux un cône de guidage vers l'espace central 27.According to Figures 3 and 4, the carriage 23 (shown schematically in Figure 1) supports the electrode holder assembly consisting in particular of two housings 25 and 25 'in the form of a tetrahedral pyramid. This pyramid comprises in particular downstream, that is to say in the direction of advancement of the animal symbolized by the arrow F1, a flank 26 and 26 ', the two flanks 26 and 26' constituting between them a guide cone towards the central space 27.

Chaque boîtier tétraédrique 25 et 25' constitue ainsi un carter de protection isolé électriquement et à l'intérieur duquel peut se positionner une des deux électrodes 28 et 28' débordant vers l'espace central 27 à travers l'arête ouverte 29,29'.Each tetrahedral casing 25 and 25 ′ thus constitutes an electrically insulated protective casing and inside of which one of the two electrodes 28 and 28 ′ can be positioned projecting towards the central space 27 through the open edge 29,29 ′.

Comme vu sur la figure 4 les électrodes 28 et 28' débordent légèrement par rapport à l'arête 29 et 29' de sorte que automatiquement la tête de l'animal viendra se positionner entre les deux électrodes 28 et 28'.As seen in FIG. 4, the electrodes 28 and 28 ′ protrude slightly relative to the edge 29 and 29 ′ so that the head of the animal will automatically be positioned between the two electrodes 28 and 28 ′.

On comprend en effet que l'animal avançant, étant entraîné par les convoyeurs 3 et 4, dans le sens de la flèche F1 va rencontrer le cône de guidage constitué par les deux flancs latéraux 26 et 26'.It is in fact understood that the advancing animal, being driven by the conveyors 3 and 4, in the direction of the arrow F1 will meet the guide cone formed by the two lateral flanks 26 and 26 '.

Ces deux flancs sont orientés de façon à conformer un volume divergent vers le bas et vers l'arrière ; ou en d'autres termes convergent vers l'avant et vers le haut.These two sides are oriented so as to form a divergent volume downwards and backwards; or in other words converge forward and upward.

Ainsi la tête de l'animal est obligatoirement guidée vers le passage central 27.Thus the head of the animal is necessarily guided towards the central passage 27.

L'animal vient donc insérer sa tête obligatoirement entre les deux électrodes 28 et 28'.The animal therefore has to insert its head between the two electrodes 28 and 28 '.

On rappellera qu'à cette phase le chariot porte électrodes 23 qui est ramené dans sa position de départ par simple gravité est immobile et en position d'attente ; il est libre de ses mouvements étant guidé simplement à roulement libre sur les rails 13 et 14.It will be recalled that at this phase the electrode holder carriage 23 which is returned to its starting position by simple gravity is immobile and in the waiting position; it is free to move, being simply guided with free rolling on the rails 13 and 14.

L'animal rencontrant cette gêne que représente l'insertion de la tête à l'intérieur du passage 27 défini par les deux électrodes 28 et 28' cherche alors à se dégager en se débattant et notamment par un relèvement de la tête vers le haut.The animal encountering this discomfort represented by the insertion of the head inside the passage 27 defined by the two electrodes 28 and 28 ′ then seeks to be released by struggling and in particular by raising the head upwards.

Dans ce mouvement les électrodes vont suivre la tête de l'animal.In this movement the electrodes will follow the head of the animal.

En effet les électrodes 28 et 28' sont montées chacune sur un bras de levier 30 et 30'.Indeed, the electrodes 28 and 28 'are each mounted on a lever arm 30 and 30'.

Les bras de levier 30 et 30' porteurs des électrodes sont montés pivotants à l'extrêmité d'un coude 31,31' sur un axe de tourillonnement 32,32'.The lever arms 30 and 30 'carrying the electrodes are pivotally mounted at the end of an elbow 31.31' on a journal axis 32.32 '.

Les électrodes sont maintenues en position basse telles que représentées en trait plein sur la figure 2 par une butée d'appui définissant leur position inférieure de repos.The electrodes are held in the low position as shown in solid lines in FIG. 2 by a support stop defining their lower rest position.

Les électrodes sont libres dans leur mouvement de pivotement vers le haut étant entraînées par la tête de l'animal pour venir occuper alors une position telle que représentée en traits pointillés sur la figure 4.The electrodes are free in their upward pivoting movement being driven by the head of the animal to then occupy a position as shown in dotted lines in FIG. 4.

Dans la position telle que représentée en pointillés les électrodes assurent notamment par les picots internes 33 et .34 le contact intime et notamment électrique avec la tête de l'animal.In the position as shown in dotted lines, the electrodes provide, in particular by the internal pins 33 and .34, intimate and in particular electrical contact with the head of the animal.

Dans ce mouvement, l'ensemble porte-électrodes suspendu au chariot 3 accompagne automatiquement et librement le corps de l'animal emprisonné par les courroies latérales 1 et 1'.In this movement, the electrode holder assembly suspended from the carriage 3 automatically and freely accompanies the body of the animal trapped by the lateral belts 1 and 1 '.

Lorsque l'animal subit l'effet de la décharge électrique, son corps s'affaisse, arrivant d'ailleurs à ce moment à l'extrêmité du parcours guidé par les courroies 3 et 4 et le corps peut donc tomber par gravité pour être repris en vue des traitements et procédures ultérieurs.When the animal undergoes the effect of the electric shock, its body collapses, arriving moreover at this time at the end of the route guided by the belts 3 and 4 and the body can therefore fall by gravity to be taken up for further processing and procedures.

Mais on comprend que dès que l'animal étant anesthésié aura perdu ses réflexes, sa tête retombe et se trouve ainsi libérée automatiquement de la pression des électrodes.But we understand that as soon as the animal being anesthetized has lost its reflexes, its head falls back and is thus automatically released from the pressure of the electrodes.

On obtient ainsi un système entièrement automatique qui permet de doser le temps de passage du courant en fonction du temps de réponse de chaque sujet ; c'est le sujet lui-même qui vient ainsi se positionner dans la position optimum de réception du courant et qui déclenche par là même action de tétanisation et dès que cette action a produit son effet, ce qui se traduit par un relâchement des réflexes et un affaissement du corps, l'ensemble, par suite de la chute de la tête, puis du corps de l'animal, est ainsi amené en position de dégagement, permettant le retour des électrodes pivotant vers leur position initiale avec la fin du passage du courant.A fully automatic system is thus obtained which makes it possible to dose the current passage time as a function of the response time of each subject; it is the subject himself who comes to position himself in the optimum position for receiving the current and which thereby triggers the tetanization action and as soon as this action has produced its effect, which results in a relaxation of the reflexes and a sagging of the body, the assembly, as a result of the fall of the head, then of the body of the animal, is thus brought into the release position, allowing the return of the electrodes pivoting to their initial position with the end of the passage current.

Le système selon l'invention est donc ainsi parfaitement automatisé et tout en assurant de parfaites conditions de sécurité pour le personnel de service, libéré pratiquement de toute intervention, on assure un effet de tétanisation optimum de chaque animal, guidé automatiquement vers la position de réception et dont le temps d'électrocution est adapté à sa constitution personnelle et à son temps de réponse.The system according to the invention is therefore perfectly automated and while ensuring perfect safety conditions for service personnel, freed practically from any intervention, an optimum tetanization effect of each animal is ensured, automatically guided to the reception position. and whose electrocution time is adapted to his personal constitution and his response time.
